Deenie- I'm right there with you! I've never had a puppy before that liked to bite and nip and chew on my fingers, ankles, and toes sooo much! And what makes it worse is that his teeth are
SHARP! The only thing that works for us is spraying Grannick's Bitter Apple Spray on my hands, arms, and toes (I have to cover my whole body with the stuff
because thats the only way Wall-E won't bite me). If the bitter spray you use doesn't work, maybe try a different brand (some brands are stronger than others) of bitter spray or even try making your own home-made "bitter spray" of something that you know your pup will find sour... vinegar maybe? Just a suggestion!
